Our invention is primarily intended for use in conjunction with the milk receptacle of milking machines and is intended for placement and being suspended from the lid,

or closure, of the milk receiving receptacle with provision being provided for the passing of a refrigerating or cooling medium therethrough.

The invention consists primarily of a lid,

or closure for the receptacle and through which the lines pass for admitting suction and milk therethrough and through which the cooling medium lines also pass. A cooler is suspended from the lid that has a milk receiving and distributing trough disposed immediately below, and in registerable alignment with, the point of deposit of the milk through the lid. Holes are disposed in the bottom of the trough to permit the warm milk being drained therefrom and being deposited upon corrugated surfaces over which the same drains. These corrugated surfaces are formed by two corrugated plates disposed between two headers so as to form a plurality of assageways connecting the said headers. ooling fluid passes through, and the milk flows over these passageways.

Heretofore it has been the general custom in devices of this kind to extract the milk from the bovine and deliver the same into a closed milk receiving receptacle and when the milking has been completed, to cool the milk by pouring the same intoV a separate device. This required the exposing of the milk, 5 one or more times, in an atmosphere and under working conditions that are not conducive to the health of the user of the milk, and that is especially not conducive to the main- 40 taining of the milk in a condition to prevent the bacterial count of the milk from developing rapidly.

Through the use of our new and improved device the milk is delivered, by the receptacle and the same is cooled therein without the exposing of the milk, in the open atmosphere, and without the unnecessary handling of the same so that the milk, as soon as delivered in the milk receiving receptacle, is [C cooled immediately to thereby prevent and retard the bacterial growth within the milk content. i v i One of the objects of our invention is to eliminate time and labor in the handling of milk where milking machines are usedlin the extracting of milk'from the bovine.

A further object of-our invention consists in providing a milk cooler, that is placed within the milk receiving receptacle, of themilking machine, at which point the milk is immediately'cooled after its extraction.

A still further object of our invention consists in providing a device for the handling of milk that may be maintained'in thehighest possible sanitary condition.

l/Vith these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, and essential elements of which are set forth in the appended claim, and a referred ,-0 form of embodiment of which is ereafter describedV with reference to the drawings which accompany and form part of the specification.` f

In the drawings: y i y Fig. 1 is a side View, partially in section, of the milk receiving receptacle ,and illustrating our new and improved device, disposed there- Fig. 2 isa top, plan view, of the mechanism illustrated in Fig. 1. f

Fig. 3 is a fragmentary, sectional, side View of the top of the milk receiving receptacle and an end view, partially in section, of the milk cooler disposed therein; that is dependl ing from the closure of the milk receiving receptacle. t Y Y Like reference characters refer to like parts throughout the several views.

l is the milk receiving receptacle, having a lip or closure 2 disposed upon the receptacle with means for maintaining the same sealed; i by the placing of a compressible gasket 3 within the top of the can and the compress` ing of the lid thereupon by compression screws 4. A head 5 is disposed centrally of the lid through which the lines pass that lead to the milking machine. A valve 6 is disposed within the head. The lines that lead to the milking machine are illustrated at 7 i and 8. We place a milk cooler Within the milk receiving receptacle and secure the same to the inside of the lid. We have found splendid results may be obtained by a cooler that `is comprised of headers -9 and 10, that are spaced apart andsecured together, by corrugated plates Ll so as to form passageways connecting the headers. A cooling medium is circulated through the cooler, the same being admitted into the header 9, through the pipe, or t'ub'el2, and the cooling-medium then passes through the passageways belcirculated through the cooling device.

tween the corrugated plates l1 and passes therefromthrough the header l0 and the pipe or tube 13.

Y The cooling medium be circulated under pressure by any suitable means'as by being connected to the Water systemV or by havingf a 'refrigerant circulating therethrough bymechanical orother means.

Y A distributing trough 14 is disposed in the upperend-of the`cooler,the top `side of the same;v beingjopen and in registerable align-V ment :with thezdscharge outlet 15, that leads to the milking machine. Drain holes 16 are disposedl in thebottom of the trough and the milkdrains therethrough and flows over the corrugated; surfaces Where the heat is eX-V tra'cted'athroughthe vcooling medium being cooler may he removably secured to the lid ori'closure 2 by any suitable `means as -through the use-of fastenin'gs, as bolts 17.

While the i'orm:Y of mechanism herein shownand 4described is admirably adapted to'fulfill.. the objects primarily stated, it is'to be understood that it is not intended to con. fine the-invention to the one form Vof embodi-` ment herein shown and described, as it is susceptible of embodiment' in Various forms, all coming Withinl the scope of the claim which follows.

What We claim is A device to be used With a milk receptacle ofvthef-'class described comprising a closure for the milk receptacle adapted for making a tight fitting connection-therewith, a pair oi' headersY disposed in spaced relation and de# pending. fromv the closure, said headers being hollow,-y a plurality of corrugated plates disposed betweenL the headers and forming passageWays connecting the headers,'a trough havingA a plurality of drain holes disposed therein being disposed above the corrugated plates: and between the headers, a .valve head disposed upon the closure and being in communication with the inside of the'milk receptacle,l said head being in direct alignment with the trough, and` pipes secured to the headers for circulating. a cooling medium therethrough and through the passageways.
